Been using Mr. Buddy heaters for years and years. I wouldn't go without them now. There is just no need. Another advantage I have learned by observing is that in calm days the heat takes Ur scent with it and goes straight up....

Yes, these are OK, but without a doubt a fire hazard waiting to happen. Tip over way too easy. I use the Mr. Heater Buddy heater in my pop up blinds. We have set up 2 pop ups for my dad. 'Nam vet with and now a replaced hip. We have to shuttle him to and from the blind. We set him up with a Buddy heater hooked up to a 20lb bottle so he don't have to replace the bottle. He lights it with a long candle lighter to keep from using the BBQ clicker.
I use them in my pop ups also. My brother and I own 5 of them and use them in blinds and love them!!!! We can heat our lunch samich wrapped in aluminum foil on top and be good to go and not worry about them tipping over. I have tried to "Accidently" bump them over at home in the yard. They turn off the first instant they begin to tip back too far.
